Help on compressor quick connect

[txusa03]

Just bought a Dewalt D55146 air compressor (1.6HP Type4). Looking to add quick connect coupler to air hose but now sure compatibility since there are a few type of quick connect (type M, V, T, Universal).

The Dewalt manual said the compressor comes with two 'univeral' quick connect that will accept styles plugs 'industrial, automotive, and ARO'.

So now I am confused as to which type lable with a single letter (M, V, T) associate with industrial vs automotive, vs ARO? Trying to figure which type of quick connect I should buy is clear as mud. Which type is the safest type.

From what i can gather, Milton is what most recommend and type V is a very secure quick connect type. Will type V fit into the Universal female quick connect or what do you recommend?

I will be using compressor for brad nailer, framing gun, and a impract wrench if that makes a difference in which connector to use. I prefer 1 type to make my life easier.

Thanks.

A is known as an industrial interchange style, probably most common.
B is what I call a long Lincoln and is basically useless
C is frequently called an automotive style, probably used more in automotive shops.
D is what I call the short Lincoln, but I think it is also known as a ARO fitting.

The universal couplings will handle the three (A, C, D) and I generally get them from Home Depot. They have brass and steel ones.

Get the type A ******* in the pics above, industrial interchange, you will have the best luck finding them in the future.

Google images will be your friend here. Personally I dont like the universal stuff, I use industrial on everything.

or Take your couplers with you to the store, and buy a style that fits in it.

...damn ninja'd

Thanks fellas. There are lots of info on this subject but I guess I just needed to know what type is considered industrial vs automotive that will fit the universal quick connect.

The more I read the more muddy it gets. So thanks for the above info.

@srmofo: The compressor comes with the universal female quick connect already installed so I want to make sure I buy the male counterpart that will fit the existing quick connect.

buy new couplers for the compressor that match whichever style you use. I use C but many use A. I've had more trouble with manufacture provided couplers than you can imagine. They often are just enough out of spec you will fight them all day so save the time and spend $2.50 each on matching couplings when you buy the males.

I Use b style just because its the oddest style avable also people dont barrow my air tools because the dont fit there connectorsi have a addaptor to a if needed

Well count me in as a "B" coupler user. My father had this style in his gas station back in the 50's and I just inherited the style and have been using it every since. I don't think I would refer to it as useless as it fits every piece of equipment in my shop. Also to make the connection all you have to do it push the couplings together, you don't have to slide the collar back to make the connection and if you're pressed you can do this with one hand. That to me is the biggest plus. If I hire someone that needs access to my air system I have plenty of fittings to put on their equipment if that is necessary. But useless, not really.......................

Industrial on all my stuff...

I've never seen a "B" style.

Got to say it, this has been one of the more helpful posts I've read in a while.

Thanks for the info.

Ive used A & C. Started out with A since they're everywere it seems. Car mechanic told me he only uses the C because in mechanics school he was taught the Industrial versions tend to leak a bit when air tools/lines are placed in tight places.
I guess when the hose/connectors bent backwards? Guess its why the automotive version was made with the wider lip????
Industrial types are designed for assembly lines and open shop areas he was told.
In a shop with alot of guys using up air it would matter but most garages it shouldt matter imo. Didnt know B snapped in without pulling the collar back, I like that idea.

A and D are the most used. A lot of Auto shops use B around here. C is what most roofers Use .

 

[Manganos]

"C" is really a "T" I believe. That is what I use.

A for everything here, 1 universal coupler just in case... well truthfully , it was on a hose that I picked up for free.

 

[theoldwizard1]

Industrial (Fig A) on my all stuff at home. No problems mixing couplers or studs from over 30 years ago with stuff I have bought recently from HF.

We use automotive in my shop and I want to upgrade the CFM and couplers in my garage. I already have 3/8" hoses everywhere but they're all stepped down to 1/4" couplers choking off my air tools!

I'm looking for 3/8" Brass Automotive couplers. Can't find them on Grainger or Graybar's online sites... Any suggestions?

Heres Milton "V" Hi-Flow series that are much larger I.D. so I think I'll give them a shot. No doubt they will be less restrictive. The M vs V picture shows how much bigger they are inside. Looks like 3/8 vs 1/4 fittings but its not, they are the same size 1/4 npt.

At my mom & pop hardware store there were some Milton brand couplers labeled "I/M", which I assume means "industrial/Milton"? Anyway, that's what I use for everything, even though until now I wasn't quite aware of it ! LOL

All I have to say is remember what Fonzie said. Aaaaaaaaaaaaaaaaaaaa.

 

[stroked383z28]

Milton V hi-flow fittings here. Highly recommended, money well spent.

I work in manufacturing and have only ever seen C type in use. I've come across A type once when I needed a male for a blow gun and grabbed one out of the maintenance shop without looking at it.
